The plating is called Ion Plating or IP plating which s one of the newest and most advanced plating now available. It produces a harder and more durable coating with a higher brightness than that produced through traditional plating methods. Experiments have proved that the plating obtained through IP plating is five to eight times better than that obtained through conventional methods in terms of wear and corrosion resistance.
As long as the tungsten does not in contact with chemical, like acid, at all time, the plating will last for long time.
